英文摘要Magnetic anomaly analysis is an important method to study the structure of deep crust. With the assumption of random magnetization sources, the structure of a magnetic layer can be inverted via spectral analysis. Curie point depth (CPD), the depth at which rocks lose their ferromagnetic properties, is the bottom of a magnetic layer. In this study, we estimate from the magnetic anomaly data of EMAG2 dataset the CPD and the top of the magnetic layer in North China. With a moving window of 180 km x 180 km, we calculate the average top and centroid depth of the magnetic layer in each window and determine the regional CPD distribution across North China. The CPD of North China varies from 18 to 32 km. In addition, the CPD in the western part of the North China Craton is deeper than that in the eastern part. The shallowest CPD is located near the Bohai Sea. When compared to available heat flow data, the estimated CPD values are consistent with thermal conductivity of 1.8-3.2 Wm(-1) K-1 and on heat production value of 0.4-1.3 A mu Wm(-3).
